Title: Liquid film type ion sensor
Inventor: TAGUCHI TOSHIYUKI
IPC: G01N27/333
Filed: 1988-03-18
Abstract: PURPOSE:To obtain the ion sensor which is highly durable and is usable stably over a long period of time by using polyester of a specific mol.wt. formed by condensation polymn. of dicarboxylic acid and dihydric alcohol as a plasticizer to be added to an ion-sensitive film. CONSTITUTION:Both electrodes of a source 12 and a drain 13 are formed on a silicon substrate 11. An SiO2 film 14 and an Si3N4 film 15 are adhered atop the substrate 11. Further, the ion-sensitive film 16 is provided to the film 15 and the circumference thereof is covered by silicone rubber 17 for the purpose of insulation and protection. The polyester of 1,000-8,000mol.wt. formed by the condensation polymn. of the dicarboxylic acid and dihydric alcohol is used as the plasticizer to be added to the film 16. This polyester interacts the objective ion in an aq. soln. and the ion-sensitive film by dissolution of the ion- sensitive film therein. Since the mol.wt. thereof is large, the polyester has excellent migration resistance and extraction resistance and is usable stably over a long period of time.

Title: Axial fan
Inventor: KIKUCHI YASUBEI
IPC: F04D29/68
Filed: 1979-05-30
Abstract: PURPOSE: To prevent generation of vortexes and noise by respectively forming diffusion vent channels between alternately arranged oblique main blades and oblique rectifying blades whose every external face slants at an attack angle smaller than an attack angle of the external face of the main blade.  
     CONSTITUTION: Extending along one face of an oblique main blade 3, each oblique rectifying blade 6 whose external face 6' slants at an attack angle is lapped over the oblique main blade 3 side by side with a vent channel 5 or a diffusion one located between those blades 3, 6. The attack angle of the external face 6' of the oblique rectifying blade 6 is determined smaller than that of the external face 3' of the main oblique blade 3. While passing through the vent channel 5, flows 7 can be rectified so that no vertex is allowed to appear on the external side of the blade (at the back of a turning blade) during rotation of an exial fan. Consequently noise emitted from the fan can be reduced.

Title: Damper device for throttle valve
Inventor: NAKAMURA AKIRA
IPC: F02D35/00
Filed: 1995-03-24
Abstract: PURPOSE: To prevent occurrence of engine stall by providing a first cylinder device against which a control member interlocking with a throttle valve lever can freely abut and a second cylinder device against which the throttle lever can freely abut, and thereby decelerating valve closing speed a little before full close. CONSTITUTION: In order to start deceleration from the state where a throttle valve 3 is fully opened, the throttle valve 3 is rotated clockwise through a throttle valve lever 4. The lever 4 abuts against a tip end of a piston rod 24 of a second cylinder 16 when the throttle valve 3 shows substantially an idling opening. A control member 6 is also rotated clockwise at this time, so that a piston rod 12 of a first cylinder 7 is released from pressing force of the lever 4, and can be freely projected. When the lever 4 pressurizes the piston rod 24 in a contracting direction in such a state, fluid inside the second cylinder 16 is compressed. Rotational speed of the lever 4 is reduced, and opening speed is decelerated.

Title: Manufacture of honeycomb core panel
Inventor: IKENAGA KEIICHI
IPC: B32B3/12
Filed: 1984-04-05
Abstract: PURPOSE:To make a honeycomb core panel free from poor adhesion between the honeycomb core and a surface board by stacking and pressurizing honeycomb core panels through a flexible spacer. CONSTITUTION:When a number of honeycomb core panels A are stacked, a flexible mounted thin spacer 5 is interposed therebetween A. The spacer 5 is made of rubber, soft foam material or the like. The spacer 5 may be entirely even in the thickness. In this method, the spacer 5 pushes up the honeycomb core 2 from the under surface thereof to close a clearance 4 formed between a surface board 3 and the honeycomb core 2. Thus, in the stacking and pressurizing of the honeycomb core panels A, the interposition of the spacer 5 allows the perfect contact between the surface board 3 and the honeycomb core 2 to accomplish uniform dispersion of pressure thereby preventing poor adhesion between the surface board 3 and the honeycomb core 2.
